There are well over 100 technical rock climbing routes on Crane Mountain. Most of them are under 100', single pitch lines between 5.5 and 5.10.
The most accessible routes lie on cliffs beside the main hiking trails: the Viewpoint Slabs and the Summit Ridge cliffs. However, since 2008, many stellar routes have been climbed east of the trails, along a path leading to the Black Arches Wall.
